Abstract

Under high-resolution, the asymmetric mode of Ge2O in germanium shows Ge isotope shifts related to Ge mass or to anharmonicity changes. We present here evidence of very small shifts between the position of lines in natural Ge and in quasi-monoisotopic Ge which are related to the change of the average mass of the matrix and we propose an explanation for this.
